Research Progress of Hydration Catalyst for Cyclohexene to Cyclohexanol
The research progress of three different types of hydration catalysts,such as mineral acid homogeneous catalyst,ion exchange resin and zeolite catalyst used in the industrial production process of cyclohexene to cyclohexanol,was reviewed.The ZSM-5 molecular sieve catalyst commonly used in the process was introduced in detail from the aspects of structure characteristics,synthesis methods and influencing factors.It provides reference for improving the performance of catalyst in hydration process and the yield of cyclohexanol in industrial production,clarifying the reaction mechanism of molecular sieve and developing new molecular sieve catalyst.
